The forming plungers and the discharge plungers operate at the same speed. Thus, as each pair of crystals isformedLtheapreviously ormed pair of 'crystals are ejected from the apparatus. Any suitable mechanism for imparting to the plate 6 an intermittent rotary move ment may be employed. The mechanism shown in the drawing comprises a shaft 28 supported in a bearing 29,` which shaft is driven from a pulley 30 having a frictional clutch connection 31 with the shaft. The shaft is resiliently connected with the plate 6 by a torsion spring 32, thereb providing an even and constant torque on t e plate 6.

The plate 6 is provided with an escapement mechanism which automatically brin into registration with t e forming dies and holds the plate in this position until the dies have compressed the ice and then retracts to clear the Plate and .also the lungers 20 to eject tlliln previously for shapes This escapement mechanism may be of any suitable construction, that shown in the drawing comprising. an escapement bar 33 mounted in a bracket 34.- rigidly supported within the housing and raised by a lspring 35.
